Jørn Christian is a Norwegian expression that goes all the way back to the vikings. Jørn means the hardcore viking that sailed across the seas and fought and plunderd. Very simular to definition Berserk. This Viking got his middle name after endless conquests of widdows across the whole northern hemisfare. The name Christian is accutally top score of a counting system used by the Vikings.

O my god, that guy just reached the ultimate score.

You could say,

O my god, that guy just reached Christian.

If the guy also can be discribed as a hardcore Norwegian viking, he deserves to be called a real Jørn Christian.
